If you are looking for an alternative cheap, electric and portable, evaporative air conditioners or also known as evaporative coolersThey are the best options you can buy.
They generate fresh air and their electricity consumption is not as high as that of air conditioners, something very important at a time when the price of electricity skyrockets due to its high consumption.
How does an evaporative cooler work?
They come in all sizes and designs you can imagine, there are even models of evaporative coolers that are designed to be used outdoors and not indoors.
Due to its name you will have already realized that it has something to do with the evaporation of water. This type of air conditioning system cools the air thanks to the evaporation of water.
All include a large water tank that you must fill depending on its size, the most normal models for interiors they usually last between 6 and 12 hours of usebut the biggest ones can last longer because they are bigger.
You do not need any type of system that expels air or humidity to the outside, as air conditioners do. The water goes through a filter and when the hot air passes through it, it evaporates the water, cooling the air on the way to being expelled.
Some models allow you to put frozen water containers at one point or put ice directly so that the water passes even colder through the filter.
